CCPP Framework Meeting Minutes 2020 11 10

Agenda

• cap_gen.py progress
• transition to cap_gen.py
• other business

cap_gen.py progress

• Steve created the long-awaited PR for Julie; cap_gen.py can now parse ccpp-table-properties and dependencies
  • Dom forgot to review it, doing today
• now working on build (see GitHub issues), then code generation

Transition to cap_gen.py

• Updated DTC timeline and resource chart (https://docs.google.com/spreadsheets/d/1XbSF1ejYcPMrVtZtk1OSiMX-vI5srLkwEUhyAirGr8k/edit?usp=sharing)
• Things that need to happen for transitioning UFS to cap_gen.py (https://docs.google.com/document/d/1M3mCO3ESR9OJqLyUbQf-ahJtmfmGKilZlWaBTxsfMRk/edit?usp=sharing)
• Follow up on discussion of last week on removal of optional arguments (or not)
• timestep_init, timestep_finalize - issue with too long subroutine names in Fortran
  • internally use tsinit and tsfinal?
  • happens frequently with SCM, but only created warnings not errors - different compiler (GNU vs Intel)? 39 | function FV3_GFS_2017_gfdlmp_regional_c768_fast_physics_timestep_init_cap() result(ierr) | 1 Error: Name at (1) is too long
  • we could set limits of 15 or 20 characters for the suite name, and similar for the group name
    • truncate using some logic, and then put the full name in a comment
    • recommend users to use shorter names for suites and groups to avoid having their cap names truncated
• Consolidation of standard names (Ligia and Grant) - https://docs.google.com/spreadsheets/d/1kWDC7_2sagm-PTP_tXaGyI3O3sJFK8FY9FElQbb6V3o/edit#gid=613941307
